as with any car on ebay i would go and have a good look at it first

few points to think about are :

there is normally a reason its been on there 3 or more times and not normally a good reason either

no V5

but on face value it looks tidy enough , had 3 owners , low(ish) mileage and full history

its probably worth a look but doubt he will swap with the st200 as it says he needs to sell to pay off debts
